Once securely tightened we push the in and outflow tubing over them and clamp them down with the supplied clamps or as in my case I opted to use my own worm drive clamps. We now can startup the PC. It's pretty wise to only activate the pump if possible (hotwire the PSU) so you know for sure there are no leaks and you have the coolant distributed efficiently everywhere.

We have a 1800 Liters per hour pump with 3/8", in our case we are pretty secure. and the water-flow was completed within seconds after starting up the PC.

I always state, if you go for water-cooling .. get cold-cathode UV blacklights and UV reflective coolant. It is just downright beautiful to look at.1

To me that can be described in one word; sexy.

Oh well, one more as the card ready and waiting for a big ass spanking from our test-system.
